Question about deadspace pockets and combat probes

When you scan down a ship in an ungated deadspace pocket (e.g. Besieged Covert Research Facility), are you then able to warp directly on top of the ship or only to the site's beacon? I'm asking because this game has some inconsistent behavior when it comes to deadspace sites, where you can warp at range to them (sometimes only using a fleet trick) but cannot warp within them or use a cyno.
